I found this on sale in a retail store.
I had a major paint job to do, so I decided to give it a try.
I was painting an interior house room, with latex paint.
The item sucked up the paint into it's reservior without any problem.
The trigger handle feed paint smoothly.
No leaking of paint was experienced at any part of the unit during the painting job.
The paint fed well out of the roller without any problem.
Coverage was uniform.
Cleanup was fairly quick with the unit itself.
The head/roller took a bit longer to get totally cleaned.
(I wanted to make sure it was totally clean, as I needed the unit for a future painting job and went with a "better-safe-than-sorry" approach.
I did not know availability of the roller head as a separate item, nor what the pricing on it may be; so I rinsed the head several times).
In my case, I had a good experience with the item.
In any painting job, there are so many different
applications, variations, indoor vs outdoor, rough surface vs smooth, and other variables involved.
That could be why some users had problems, vs my experience of no real problems (other than the head requiring several rinsings).
I have to give it a thumbs up!
For the price and ease of use, I have done better with this item than with some lower end electric and/or battery powered spray painting units.
The paint shield did a good job. In my case it fared well.
